CX to SIRII Wiring

[MugenRacer]

I know that the 92 are supposed to come with the VTEC already in the ecu to engine harness but I am needing assistance with the engine harness I am trying to convert the CX harness and here are my questions:

1. The knock sensor location on the engine harness is already taking by the same color as the B16 SiR2 Harness I have (it wont work for it was pretty well hacked but I use it as refernce)

2. The CX harness has a 2 wire O2 and the SiR2 is a four wire... Help what are the ECU or Engine harness pinouts?

3. Does anyone have diagrams or know of a place online with diagrams of both ECU side and Engine side pinouts?

TIA

1) the civic harnesses do not have knock sensros wired. you will have to wire that up on your own, even on a 92.

2) you need to buy a 4-wire o2 sensor (if your swap didn't come with one) and hard wire those into the ECU
You add 3 wires to the engine harness using the 4 wire O2 connector and wire the following:
- ORG/BLK wire goes to A6, which is Heater Control
- GRN/WHT wire goes to D22 which is Sensor Ground
- YEL/BLK wire goes to A25 which is Sensor Positive

3) check our swap section and articles section
